Hi, IB noob here.  Wanting to build a small IB for my HT and wondering if my pair of Ascendant Audio Atlas 12 subs would be suitable to build an IB. I think these are the T/S values for the sub, but im not completly sure. Qts: 0.219 Qes: 0.242 Qms: 2.266 Fs: 18.856 Hz Re: 6.26 Ls: 7.382 mH Lp: 9.456 mH Rp: 14.68 Dia: (% shift) 250 m 33.2 % Vas: 142.7 L Mms: 168.8 g Cms: 421.9 u Bl: 22.74 T*m n0: 380.1 m SPL: 87.79 dB Sd: 0.0471 m^2 Xmag: 26.0 mm Xmax: 24.2 mm |

Need to know more about the space where the sub will be used.
That driver if the specs are right has a very low Qts. Not ideal for IB.

Oh poppycock! low qts can be dealt with. especially with the atlas drivers. They have a "dummy" VC that depending how it is configured will raise qts However only a pair of 12s will lack any real output unless it is a small room. |

The drivers will be above the "stage" area in the attic with the opening in the ceiling. On the T/S specs I will have to contact Chad or Dale over at Ascendant to get them again. I though those were the number for the Atlas 12, But as I said in the opening thread, I was not completely shure. Here is a pic of location. It's a top view:  |

If there is a cheap option to replace the 12's I already have please suggest. Otherwise I'd like to stay with the Atlas 12's until the budget allows it. |

Thanks. Then what would be an inexpensive option, driver wise, to move into the IB world ? |

What do you consider 'inexpensive'?
And are you locked into using 12" drivers or can you go larger?

Ask TC-Sounds if the 15" TC-1000s are available, if so there's nothing close to that price for a good 15"s. The Qts is too low, but getting the DVC version allows you to raise the "Q" just like you could with the Atlas 12"s www.tcsounds.com/tc1000.htm |

Doesn't look like it's available  If I increase my budget slightly for the drivers (take from my amp budget). What other good options in 15" might I have that won't break the bank ?? |

Any other inexpensive 15" driver recommendation? TC Sounds' won't answer emails or their phones.
I'll look into the MAW-15

Try eBay, Cerwin Vega HED 15's model up pretty well for an IB and you can get a pair for about 200 shipped.

People need to stop ragging on TC-Sounds. They're not a big company. They only recently launched direct sales and they're having teething problems as a result of the popularity of the drivers.
If you're that impatient I can turn you on to other companies, but you'll pay twice as much.
Which would you prefer?
